SPACE AND VENTILATION REQUIREMENTS.
(a)Ten square feet of shelter floor area per person shall be provided.
(b)At least 65 cubic feet of space per person shall be provided.
(c)If the shelter capacity is based on minimum space requirements, then at least
three cubic feet of fresh air per minute per person are required.
(d)No filters are required on mechanical ventilation systems other than those
necessary for the normal daily use of the space. Ventilation systems should
be designed to prevent an effective temperature exceeding 85 Fahrenheit.
Wherever practical, owners should design for this condition by increasing the
fresh air supply rather than through air cooling and humidity control equipment.
